Definition of Aperture

In the context of graphic design, “aperture” refers to the opening or negative space within or between characters in a typeface. It is the partially enclosed, somewhat rounded negative space found in characters such as ‘n’, ‘c’, ‘s’, or the fully enclosed space within an ‘o’ or ‘b’. The aperture affects legibility and the overall feel of the typeface, influencing how type interacts with the design elements around it.


  • Counter: The fully enclosed or partially enclosed space within a letterform, such as the space inside an ‘o’ or ‘e’, which is related to but distinct from the aperture.
  • Open Aperture: Refers to typefaces with wider openings, which can enhance legibility, especially in smaller sizes or at a distance.
  • Closed Aperture: Describes typefaces with narrower openings, creating a more compact and sometimes more elegant appearance, but potentially reducing legibility.


The aperture in graphic design plays a crucial role in readability and the character of a typeface. It influences how text will be perceived in different contexts, such as in print, on web pages, or in logos. Understanding aperture can help designers choose typefaces that complement the overall design, convey the intended message, and ensure that text remains legible across various applications and sizes.

Usage Tips

  • Legibility: Consider the aperture when selecting a typeface for body text, especially for digital screens or small print, to ensure that text remains readable.
  • Aesthetic and Mood: The aperture contributes to the mood and tone of the design. Open apertures tend to feel more friendly and accessible, while closed apertures can appear more formal.
  • Contextual Harmony: Match the aperture of your typeface with the design’s context and intended message, ensuring it harmonizes with other design elements.

Related questions about aperture

  • How does aperture affect the legibility of a typeface?
    The aperture affects legibility by determining how much negative space is available within and between characters, influencing how easily individual letters can be distinguished from one another.
  • Can the aperture of a typeface influence the tone of a design?Yes, the aperture can significantly influence the design’s tone; open apertures tend to convey a more open and friendly tone, while closed apertures can suggest sophistication and exclusivity.
  • How should aperture be considered when designing for digital screens?
    When designing for digital screens, consider typefaces with larger apertures to enhance readability, especially at smaller sizes or lower resolutions.
  • Is there a rule of thumb for matching aperture with design style?
    While there’s no strict rule, a good practice is to match the aperture to the design’s intended mood and functionality; open apertures for clarity and accessibility, closed apertures for elegance and formality.
  • How do different apertures impact the spacing and layout of text in a design?
    Different apertures can affect text density and white space in a layout; open apertures may require more space to maintain legibility, while closed apertures can allow for tighter text layouts without compromising the design’s aesthetic.
